Jira issue: CRDB-65747

Start with pkg/server/node.go at allocateStoreIDs (line 440), initializeAdditionalStores (lines 989-991), and Node.start (lines 764-765), then trace the replica-unavailable path in pkg/kv/kvserver/replica_circuit_breaker.go and replica.go cited by the stack trace. Use the Sentry report and Jira CRDB-65747 to establish the failure conditions; done means identifying the root cause and an agreed fix for the initialization failure.
